  * stupidity. If called any time but when then ISO C standard specifically
  * allows it, all hell can and will break loose, especially with threads!
  *
  * This implementation ignores all arguments except the buffering type,
  * and uses the existing buffer allocated alongside the FILE object.
  * In the case of stderr where the preexisting buffer is length 1, it
  * is not possible to set line buffering or full buffering. */
